Patent number: 9661938Abstract: A foldable frame assembly for a playpen includes a collapsible bottom frame which has a central support mount, a plurality of linking elements, a plurality of first linking rods and a plurality of second linking rods. The linking elements are pivoted between the central support mount and the lower end of the plurality of pillars respectively. Each of the linking elements is provided with a sliding part for moving along the linking elements. When the central support mount was lifted upward, the second linking rods are associated with the first linking rods through the sliding parts thereby incurring an inward torque to prevent the pillars from deflecting outward. By such of the inward torque, users can save their troublesome of stretching hands to hold and keep the pillars uprightly while converting the playpen into its folded configuration.Type: GrantFiled: March 25, 2015Date of Patent: May 30, 2017Assignee: Dorel Juvenile (Zhongshan) Product Co., Ltd.Inventors: Sheng-Po Hung, Yu-Wen Wang, Chen-Tai Chang

Patent number: 8915516Abstract: A convertible tandem stroller frame is capable of locking in a tandem stroller mode for installing a second seat thereby concurrently transporting two occupants, and capable of converting said mode into a single seat mode for transporting single occupant by simply manipulating a release actuator at a front portion of the convertible tandem stroller frame. The convertible tandem stroller frame may include a front rack, a rear rack, at least a longitudinal telescopic mechanism and at least a locking mechanism. The front rack and the rear rack are lockably and adjustably connected by the longitudinal telescopic mechanism, so as to be extended into the tandem stroller mode and be retracted into the single seat mode. The locking mechanism is associated with the release actuator for locking and un-locking the longitudinal telescopic mechanism by manipulating in front of the convertible tandem stroller frame.Type: GrantFiled: March 4, 2013Date of Patent: December 23, 2014Assignee: Lerado (Zhong Shan) Industrial Co., Ltd.Inventors: Cheng-Fan Yang, Chen-Tai Chang, Sheng-Po Hung, Fu-Peng Chou

Publication number: 20140366276Abstract: A baby bouncer with a width variable frame is configured to have an erected configuration for use as a regular baby bouncer, and a folded configuration for reducing the width of the baby bouncer when being not in use. The frame of the baby bouncer includes at least a base frame, a pair of bouncing support rods and a baby carrier frame. The base frame and the bouncing support rods are associated by two gear elements. By meshing the first gear element and the second gear element, the bouncing support rods and the bouncing support rods are capable of simultaneously rotating in an opposite direction either in erecting or folding of the baby bouncer. When need to fold the frame of baby bouncer into the folded configuration, care-giver may unlock two lockable joints of the baby carrier frame and fold to associating the bouncing support rods and the base frame.Type: ApplicationFiled: June 13, 2014Publication date: December 18, 2014Inventors: YI-WEI CHANG, CHUNG-MING TSAI, FU-PENG CHOU, SHENG-PO HUNG, CHEN-TAI CHANG
